Usefulness of the Infant Driven Scale in the early identification of preterm infants at risk for delayed oral feeding independency

Developing the Mansoura Early Feeding Skills Assessment Scale for Preterm Infants

Purpose

This study aimed to develop a new bedside scoring system scale that assesses preterm infants' oral feeding skills (OFS) in the neonatal intensive care unit (NICU).

Methods

A literature review and critical appraisal of available oral feeding assessment tools/scores were performed. Subsequently, we developed the "Mansoura Early Feeding Skills Assessment" (MEFSA) scale, an 85-item observational measure of oral feeding skills with three main sections. Forty-one preterm infants who did not receive oral feeding but were clinically stable enough to initiate oral feeding were included in the study. Next, we applied and interpreted the MEFSA to describe and score their feeding skills.

Results

Applying the MEFSA resulted in a smooth feeding transition, early start of oral feeding, full oral feeding, and discharge with a shorter period of tube feeding in preterm infants.

Conclusion

The MEFSA is a successful bedside scoring system that assesses the OFS of preterm infants in the NICU.

Preterm infant cues during breastfeeding and its measurement: A scoping review

Background

Preterm infants display certain behaviors to communicate their needs, known as preterm infant cues. However, the existing research on preterm infant cues primarily draws from studies conducted on bottle-fed infants rather than breastfed infants.

Objective

This study aimed to investigate the concept of preterm infant cues during breastfeeding and its appropriate instruments.

Design

A scoping review.

Data Sources

The articles published up to January 2022 were searched from multiple sources from EBSCOhost Web, namely CINAHL Plus with Full Text, MEDLINE, ERIC, and E-Journals.

Review Methods

The articles retrieved for this review were screened using PICO (Population, Intervention, Comparison, and Outcomes) format. Preferred Reporting Items for Systematic Reviews (PRISMA) checklist was used in selecting the articles, and Joanna Briggs Institute Critical Appraisal was utilized by two independent authors to assess the articles' quality. A descriptive method was used to analyze the data.

Results

The initial review stage found 183 potential articles, but only four satisfied the criteria. The notion of preterm infant cues during breastfeeding is centered on the actions of preterm infants while positioned on their mother's chest. These feeding cues are identifiable before, during, and after breastfeeding and include cues for hunger, self-regulation, stress, satiation, approach, avoidance, and sucking quality. To effectively recognize these cues, tools such as the Preterm Infants Cues Coding System (PFCCS), Infant Driven Scale (IDS), Newborn Individualized Developmental Care and Assessment Program (NIDCAP), and Preterm Breastfeeding Behavior Scale (PIBBS) can be utilized.

Conclusion

The study findings highlight the importance of recognizing preterm infant cues during breastfeeding to facilitate proper feeding and developmental care. Observational studies have proven to be an effective means of observing these cues during breastfeeding. By leveraging the cues identified in this review alongside tools such as PFCCS, IDS, NIDCAP, and PIBBS, nurses can accurately interpret preterm infants' breastfeeding cues in neonatal care settings of all levels. This, in turn, can aid in developing care plans that promote better feeding ability outcomes.

Effect of cue-based feeding on time to nipple feed and time to discharge in very low birth weight infants

The objective of this study is to evaluate the effectiveness of a cue-based feeding protocol in improving time to nipple feed and time to discharge in very low birth weight infants in a Level III Neonatal Intensive Care Unit. Demographic, feeding, and discharge data were recorded and compared between the two cohorts. The pre-protocol cohort included infants born from August 2013 through April 2016 and the post-protocol cohort included infants born from January 2017 through December 2019. 272 infants were included in the pre-protocol cohort and 314 infants in the post-protocol cohort. Both cohorts were statistically comparable in gestational age, gender, race, birthweight, prenatal care, antenatal steroid use, and rates of maternal diabetes. There were statistically significant differences between the pre- versus post-protocol cohorts in median post-menstrual age (PMA) in days at first nipple feed (PO) (240 vs 238, p = 0.025), PMA in days at full PO (250 vs 247, p = 0.015), and length of stay in days (55 vs 48, p = 0.0113). Comparing each year in the post-protocol cohort, for each outcome measure, a similar trend was noted in 2017 and 2018, but not in 2019. In conclusion, the cue-based feeding protocol was associated with a decrease in the time to first PO, time to full nipple feeds, and the length of stay in very-low-birthweight infants.

Implementing an Evidence-Based Feeding Protocol: Impact on Nurses' Knowledge, Perceptions, and Feeding Culture in the NICU

BACKGROUND

Evidence-based feeding practices are often variable among neonatal providers due to lack of knowledge and neonatal intensive care unit (NICU) feeding culture norms.

PURPOSE

To evaluate changes in NICU nurses' knowledge, perceptions, feeding practices and culture following education about, and implementation of, an evidence-based Infant-Driven Feeding (IDF) protocol.

METHODS

A pre-/postprospective comparative design was used to survey 120 registered nurses employed in a level 3 NICU about feeding practices, knowledge, and culture prior to IDF education and 1 to 2 months after IDF implementation.

RESULTS

The preeducation survey yielded 59 respondents; of these, 30 responded to the same survey after IDF implementation. Postimplementation responses were significant for fewer nurses making decisions to begin oral feedings ( P = .035), greater use of gestational age to increase frequency of oral feeding attempts ( P = .03), less reliance on weight loss to decrease oral feeding attempts ( P = .018), an increase in use of combination interventions to prepare infants for oral feeding ( P = .001), and greater willingness to allow a rest period or stop the feeding if an infant falls asleep after completing 70% of the feeding ( P = .03).

IMPLICATIONS FOR PRACTICE AND RESEARCH

Trends in several survey categories following the education program and implementation of IDF support the use of evidence-based practices (EBPs) such as IDF. Future research focused on nurses' perceptions of how education influences integration of specific EBPs into practice is needed. Evaluating EBP mentorship combined with education about EBPs can provide insights on how best to integrate EBPs into practice.

Clinical validation of the infant-driven feeding scales© in Turkey

BACKGROUND

Supporting the development of feeding skills among preterm infants is an important component of neonatal care. The selection of appropriate and supportive feeding interventions begins with a comprehensive assessment of the infant's skills.

PURPOSE

This study aimed to adapt the Infant-Driven Feeding Scales© (IDFS) to the Turkish language.

METHODS

This was a methodological, observational, single-center cross-sectional study. The study included 80 infants born at a gestational age ≥ 32 weeks, consecutively admitted to a tertiary Neonatal Intensive Care Unit (NICU). Research data were collected using a premature infant descriptive information form (IDIF), IDFS, and LATCH Score for Breastfeeding Assessment. For the Turkish validity-reliability of the IDF, the translate-back translate method was used with the content validity index (CVI) assessed.

RESULTS

The scale had CVI values between 0.90 and 1.00 with a mean CVI = 0.96. For measures 1 and 2, there were significant positive and high-level correlations between IFDS-R and IFDS-Q correlation values (r = 0.553-0.958; p = 0.001) and significant negative, low-level correlations between IFDS-R and IFDS-Q with the LATCH scale (r = 0.439-0.532; p = 0.001). According to inter-observer compatibility analyses, the kappa value was 0.94-1.00 for the first measure and 0.96-1.00 for the second measure (p = 0.001). There were negative significant correlations between IDFS-R points with gestational age and postmenstrual age (PMA) (p = 0.001), and gestational age and PMA were explanatory factors for 13.8% of IDFS-R points (F = 7.30, p = 0.001).

CONCLUSIONS

The IDFS is recommended for use as a valid and reliable tool to ease the safe and successful development of oral feeding skills in preterm infants and to plan evidence-based interventions.

IMPLICATIONS FOR PRACTICE

The IDFS appears to be a beneficial measurement device for use in assessing the state of readiness of preterm infants for oral feeding and for early determination of risks that may occur due to delayed feeding independence of infants.

Psychometric properties of the oral feeding assessment in premature infants scale

Professionals that work in neonatal units need to identify the strengths and weaknesses of the premature infant who is in the transition process from feeding through a gastric tube to oral feeding. The main aim of this study was to validate the Oral FEeding Assessment in premaTure INfants (OFEATINg) instrument. A psychometric validity and reliability study was conducted in Neonatal Intensive Care Units of two public, metropolitan, university hospitals. The study population were premature infants at a postconceptional age of 31-35 weeks. The study included evaluation of the reliability, convergent, discriminant and construct validity, sensitivity and specificity of the OFEATINg instrument. A total of 621 feedings of 56 preterm infants were evaluated. Confirmatory factor analysis identified 3 factors and 13 indicators with a good fit to the model. Cronbach's alpha coefficient was 0.78. The instrument showed high indices of inter-rater reliability (Pearson 0.9 and intraclass correlation coefficient 0.95). The OFEATINg scale is a valid and reliable instrument for evaluating the readiness for oral feeding of preterm infants. It may enable clinicians to evaluate the physiological and behavioral abilities involved in the oral feeding process and help them make decisions related to the transition to full oral feeding.Clinical trial registration: This study was prospectively registered at the two Institutional review boards.

Improving Time to Independent Oral Feeding to Expedite Hospital Discharge in Preterm Infants

BACKGROUND AND OBJECTIVES

Achievement of independent oral feedings remains the most common barrier to discharge in preterm infants. Early oral feeding initiation may be associated with a lower postmenstrual age (PMA) at independent oral feeding and discharge. In preterm infants born between 25 and 32 weeks' gestation, our aim was to decrease the PMA at independent oral feedings and discharge by 1 week between June 2019 and June 2020.

METHODS

Following formation of a multidisciplinary team, the following plan-do-study-act cycles were targeted: (1) oral feeding initiation at <33 weeks' PMA, (2) cue-based feeding, and (3) practitioner-driven feeding in infants who had not yet achieved independent oral feedings by 36 weeks' PMA. Outcome measures included the PMA at independent oral feeding and discharge. Process measures included adherence to cue-based feeding assessments and PMA at oral feeding initiation.

RESULTS

In total, 552 infants with a median gestational age of 30.3 weeks' (interquartile range 28.1-32.0) and birth weight of 1320 g (interquartile range 1019-1620) were included. The PMA at discharge decreased from 38.8 to 37.7 weeks during the first plan-do-study-act cycle, which coincided with an increase in the number of infants initiated on oral feeds at <33 weeks' PMA from 47% to 80%. The age at independent oral feeding decreased from 37.4 to 36.5 weeks' PMA.

CONCLUSIONS

In preterm infants born between 25 and 32 weeks' gestation, earlier oral feeding initiation was associated with a decreased PMA at independent oral feeding and discharge.

Cue-based versus scheduled feeding for preterm infants transitioning from tube to oral feeding: the Cubs mixed-methods feasibility study

BACKGROUND

There is a lack of evidence of the effect of cue-based feeding compared with scheduled feeding on important outcomes for preterm infants.

OBJECTIVES

The objectives were as follows: (1) to describe the characteristics, components, theoretical basis and outcomes of approaches to feeding preterm infants transitioning from tube to oral feeding; (2) to identify operational policies, barriers and facilitators, and staff and parents' educational needs in neonatal units implementing cue-based feeding; (3) to co-produce an intervention for feeding preterm infants in response to feeding cues; (4) to appraise the willingness of parents and staff to implement and sustain the intervention; (5) to assess associated costs of implementing cue-based feeding; (6) to determine the feasibility and acceptability of a future trial; (7) to scope existing data-recording systems and potential outcome measures; and (8) to determine stakeholders' views of whether or not a randomised controlled trial of this approach is feasible.

DESIGN

This was a mixed-methods intervention development and feasibility study comprising (1) a systematic review, case studies, qualitative research and stakeholder consensus; (2) the co-production of the intervention; (3) a mixed-methods feasibility study; and (4) an assessment of stakeholder preferences for a future evaluation.

SETTING

Three neonatal units in the UK (two level 3 units and one level 2 unit).

PARTICIPANTS

Developmentally normal, clinically stable preterm infants receiving enteral feeds (n = 50), parents (n = 15 pre intervention development; n = 14 in the feasibility study) and health-care practitioners (n = 54 pre intervention development; n = 16 in the feasibility study).

INTERVENTION

An evidence-informed multicomponent intervention comprising training, a feeding protocol, feeding assessment tools, supplementary training materials [including posters, a film and a narrated PowerPoint (Microsoft Corporation, Redmond, WA, USA) presentation] and the 'Our Feeding Journey' document.

MAIN OUTCOME MEASURES

The main outcome measures were recruitment and screening rates, infant weight gain, duration of the intervention, feeding outcomes, implementation outcomes (contextual facilitators and barriers, acceptability, adoption, appropriateness and fidelity) and stakeholder preferences for a future evaluation.

RESULTS

The systematic review of 25 studies concluded that evidence in favour of cue-based feeding should be treated cautiously. The case studies and qualitative research highlighted contextual barriers to and facilitators of the implementation of cue-based feeding. The telephone survey found that many neonatal units are considering implementing cue-based feeding. We recruited 37% of eligible infants, and there was good retention in the study until discharge but a high loss to follow-up at 2 weeks post discharge. The mean number of days from intervention to transition to full oral feeding was 10.8, and the mean daily change in weight gain was 25 g. The intervention was acceptable to parents and staff, although there was dissatisfaction with the study documentation. Intervention training did not reach all staff. A cluster-randomised design with a composite outcome was suggested by stakeholders for a future study.

LIMITATIONS

The intervention was available only in English. Intervention training did not reach all staff. There was low recruitment to qualitative interviews and observations. Only a small number of medical staff engaged in either the training or the interviews.

CONCLUSIONS

It is feasible to implement a cue-based feeding intervention with improved training and documentation. Further work is needed to assess the feasibility of a future trial, noting evidence of existing lack of equipoise.

FUTURE WORK

The next steps are to digitalise the intervention and conduct a survey of all neonatal units in the UK.

Positive breastfeeding experiences and facilitators in mothers of preterm and low birthweight infants: a meta-ethnographic review

Background

Most qualitative research on breastfeeding the preterm or low-birthweight (LBW) infant has focused on negative insights; there are no comprehensive insights into how, when and why mothers experience positive breastfeeding experiences. We aimed to address this knowledge gap by exploring what characterizes and facilitates a positive breastfeeding experience in mothers of preterm and/or LBW infants.

Methods

A systematic review using meta-ethnographic methods was conducted. Search strategies involved a comprehensive search strategy on six bibliographic databases, citation tracking and reference checking. The analysis involved a reciprocal level of translation and a line of argument synthesis.

Results

Searches identified 1774 hits and 17 articles from 14 studies were included, representing the views of 697 mothers. A positive breastfeeding experience was identified as being ‘attuned’. Three themes and eight sub-themes were developed to describe what characterizes attuned breastfeeding. ‘Trusting the body and what it can do’, concerned how attuned breastfeeding was facilitated through understanding the bodily responses and capacity and feeling comfortable with holding the infant and to breastfeed. ‘Being emotionally present – in the here and now’ described the importance of feeling relaxed and reassured. ‘Experiencing mutual positive responses’, illuminated how attunement was related to feelings of mutuality - when the mother recognises the infant’s cues, responds to these signals and receives a positive response from the infant. The key factors to facilitate attuned breastfeeding were opportunities for prolonged close physical contact with the infant, positive relationships with and support from staff and peers, and being facilitated to breastfeed when the infant showed feeding cues.

Conclusions

This study provides new insights into what characterizes a positive breastfeeding experience and how staff can facilitate and enable mothers to achieve attuned breastfeeding. Improvements in units’ design, such as for rooming-in and having prolonged skin-to-skin contact, and care provided by knowledgeable, supportive and encouraging staff and peers, are crucial. The mother’s physical and emotional states and the infant’s behavioural responses and physiological signals should guide the process towards positive breastfeeding practices.

A cross-sectional analysis of infant-driven and traditional feeding outcomes for neonatal intensive care unit infants

OBJECTIVE

The goal of this study was to assess the impact of infant-driven feeding (IDF) compared to traditional feeding protocols in promoting earlier successful feeding outcomes.

STUDY DESIGN

We performed a cross-sectional analysis of infants admitted to a level three neonatal intensive care unit (NICU) over a 2-year period. We compared infants fed with the traditional protocol to those under the IDF protocol.

RESULTS

Infants in the IDF group were younger at first feed (p < 0.001). There was no difference in age at nasogastric (NG) tube removal or at discharge, length of stay, or percentage breastfeeding at discharge. There were no differences in outcomes within two subgroups born at <35 and <32 weeks gestation, respectively.

CONCLUSION

The IDF program led to earlier initiation of oral feeding. However, this did not lead to earlier NG tube removal or discharge, a shorter length of stay, or increase in the rates of breastfeeding.

Development of Swallowing Function in Infants with Oral Feeding Difficulties

Background

Discharge of preterm infants is often delayed because of their oral feeding difficulties. Independent oral feeding is the last obstacle to pass after managing acute and chronic morbidities. We conducted this study to determine the prevalence, characteristics, and risk factors of swallowing dysfunction and suggest proper interventions to reduce aspiration and chronic lung injury.

Methods

Infants admitted to the neonatal intensive care unit (January 2016 to December 2018) who were performed modified barium swallow study due to oral feeding difficulties were enrolled. Modified barium swallow study was done ≥ postmenstrual age 37 weeks to limit radiation exposure. Clinical data were collected retrospectively. Swallowing dysfunction was defined as inadequate epiglottic closure, laryngeal penetration, or tracheal aspiration according to result of the modified barium swallow study.

Results

Among a total of 54 infants enrolled, nine (16.7%) were term infants, 13 (24.1%) were late preterm infants (gestational age, 34-36 weeks), and 32 (59.3%) were early preterm infants (gestational age < 34 weeks). Gestational age and birth weight were smaller in infants with swallowing dysfunction. Total duration of mechanical ventilation and duration of invasive ventilation were longer in infants with swallowing dysfunction. The risk of swallowing dysfunction increased by 11.2 times for infants with gestational age < 29 weeks compared to infants with gestational age ≥ 29 weeks. Swallowing dysfunction was improved in most infants after they became matured. They showed different time and rate of maturation with the help of rehabilitation through swallow therapy and dietary modification with thickened formula.

Conclusion

Preterm infants with gestational age < 29 weeks or with longer ventilation duration are at a higher risk of aspiration. Rehabilitation of swallow therapy and dietary modification with thickened formula can be helpful interventions to prevent aspiration and chronic lung injury and reassure parents until independent oral feeding is possible.

Management of Oral Feeding Challenges in Neonatal Intensive Care Units (NICUs): A National Survey in China

Objectives: To investigate the current practices of oral feeding difficulties facing high-risk infants in Chinese NICUs. Methods: A questionnaire to survey infant oral feeding practices was distributed to 100 level II and III Chinese neonatal intensive care units (NICUs). Results: Responses were obtained from 88 NICUs. No Units had any structured guidelines regarding the management of infant oral feeding as they transitioned from tube to independent oral feeding. In 54 (61.4%) NICUs, nurses and physicians made shared decisions on when oral feeding were to be initiated. Fifty-four (61.4%) and 22 (25.0%) NICUs used postmenstrual age (PMA) or weight at PMA as a criterion for initiating oral feedings, respectively. The top three criteria to determine introduction of oral feeding were severity of disease, presence of sucking reflex, and trial feeding success. Adverse events were used by 78 Units as indices of oral feeding difficulty. Twenty (22.7%) and 25 (28.4%) Units had access to occupational therapists or nurses who provided oral motor interventions during feeding, i.e., oral support (chin and cheek support, aid to deglutition), non-nutritive sucking with pacifier, and oral stimulation. Conclusions: The management of oral feeding issues in NICUs vary widely in China in relation to the assessment of readiness to oral feeding, daily oral feeding practices and interventions used by staff. It is proposed that an educational program focused on the physiology of infant oral feeding, available evidence-based tools and interventions would assist NICU caregivers develop structured guidelines to improve infants' safe and efficient attainment of independent oral feeding.

Factors Associated with Delayed Transition to Oral Feeding in Infants with Single Ventricle Physiology

OBJECTIVES

To describe the duration of time to achieve exclusive oral feeding in infants with single ventricle physiology and to identify risk factors associated with prolonged gastrostomy tube dependence.

STUDY DESIGN

Single center, retrospective study of infants with single ventricle physiology. The primary outcome was duration of time required to achieve oral feeding. Transition periods were defined as exclusive oral feeding by Glenn palliation (early), by 1 year of age (mid), or after 1 year of age (late).

RESULTS

Seventy-eight infants were analyzed; 46 (59%) were discharged to home with a gastrostomy tube after the initial hospitalization. Overall, 39 infants (50%) achieved early transition, 14 (18%) mid, and 18 (23%) late. The group who achieved early transition had a higher percentage of preoperative oral feeding (P < .01), greater weight-for-age z score at initial discharge (P = .03), shorter initial intensive care unit duration (P < .01), shorter initial hospital length of stay (P < .01), and greater weight-for-age z score at Glenn admission (P = .02). No preoperative oral feeding (OR = 0.12, P = .02) and greater number of cardiac medications at initial discharge (OR = 3.8, P = .03) were associated with failure to achieve early transition. No preoperative oral feeding (OR = 0.09, P = .01) and longer initial intensive care unit duration (OR = 1.1, P = .03) were associated with failure to achieve mid transition.

CONCLUSION

Preoperative oral feeding may potentially be a modifiable factor to help improve early transition to oral feeding.

Does the Infant-Driven Feeding Method Positively Impact Preterm Infant Feeding Outcomes?

BACKGROUND

Achievement of independent oral feeding is a major determinant of discharge and contributes to long lengths of stay. Accumulating evidence suggests that there is great variation between and within newborn intensive care units in the initiation and advancement of oral feeding. The Infant-Driven Feeding (IDF) method is composed of 3 behavioral assessments including feeding readiness, quality of feeding, and caregiver support. Each assessment includes 5 categories and is intended as a method of communication among caregivers regarding the infant's readiness and progression toward independent oral feeding.

PURPOSE

To identify and summarize the available evidence on the use of the IDF method at initiation of oral feeds, time to independent oral feedings, and length of stay in the newborn intensive care unit or level II nursery for preterm infants.

METHODS/SEARCH STRATEGY

Four databases including CINAHL, Medline/PubMed, Ovid Nursing, and Embase were searched for "infant guided feedings," "infant driven feeding," "cue-based feeding," and "co regulated feeding." The full text of 32 articles was reviewed to identify experimental, quasiexperimental, or retrospective design to assess the evidence related to cue-based feeding.

FINDINGS

There were no randomized control, quasi-experimental, or retrospective studies utilizing the IDF method. There were 3 quality improvement projects utilizing the IDF method. The findings were conflicting: 1 project found the IDF method favorable in the achievement of full oral feedings, 2 projects found the IDF method favorable for reducing length of stay, and 1 project did not find differences in initiation, achievement of oral feedings, or length of stay.

IMPLICATIONS FOR PRACTICE

There is scant evidence limited to quality improvement projects to support the use of the IDF method.

IMPLICATIONS FOR RESEARCH

Research is needed to empirically validate the IDF method and to inform practice related to the initiation and advancement of oral feeding for preterm infants.
